UNITED snares PATENT onrron CLINTON W. DICKINSON, OF LA CROSSE,WISCONSIN. i

PLOW.

To all whom it may concern Be it known that I, CLINTON W. DICKIN- soN, aresident of La Crosse, in the county of'La Crosse and State ofWisconsin, have invented certain new and useful Improvements in Flows,of which the following is a full, clear, and exact description.

The invention relates to plows, and more particularly to means forcontrolling thedelivery of a furrow-slice cut and lifted by the plow, tothe ground or a previously out furrow.

In a plow heretofore produced, there is embodied a guide which isdesigned to control and direct the furrow-slice cut by a concave-convexdisk, said device being movable with respect to the plow to control thedelivery of furrow-slices of different sizes and to provide for thepassage of irregular slices usually enco-untered in practies. Theaforesaid plow also embodies means for limiting the turning or twistingmovement of the furrow-slice sothat it will be delivered 111substantially true mverted position and not irregularly. The means forpreventing the excessive turning of the slice was mounted on the frameand its rela tion to the guide for limiting the outward or upwardmovement of the slice was not fixed. In practice it has been found thatfurrow-slices under the various or different conditions of the soil,will be better held and guided against excessive turning movementwhenthe means for restraining the turning of the slice is mounted indefinite or fixed relation to the guide and at the bottom edge of theguide and that such arrangement better adapts the structure for theproper. and even delivery of irregular and uneven slices or slices underdifferent conditions. a

The present invention designs to provide improved means for controllingthe furrowslice cut by the plow and consists in the several novelfeatures hereinafter set forth and more particularly defined by claimsat the conclusion hereof.

In the drawings: Figure 1 is a plan of a disk-plow embodying theinvention. Fig. 2 is a detail plan of the slice-guiding means, theshield and its support being broken away to illustrate the ledge forguiding the slice. Fig. 3 is a side elevation. Fig. l is a section online 4-4 of Fig. 3. Fig. 5 is a section on line 5-5 of Fig. 3. Fig. 6 isa section on line 6--6 of Fig. 3.

disk may be varied as desired. The disk,

as well understood in the art, is set at an angle to the line of draftand with respect to the vertical to penetrate the soil, and cut afurrow-slice which will be lifted and turned outwardly as the diskis'drawn forwardly in the soil. Usually a scraper 20 is associated withthe disk and engages the concave face thereof to cut or remove the soilfrom the disk at such point as may be desired, and its form is similarto a moldboard to cooperate with the disk in turning the furrow-slice asdesired. Scraper 20 is secured to a standard 21 which is adjustablysecured to an adjustable bracket 22 wherebythe scraper may be adjustedin different relations with the disk as well understood in the art. Thefixed member 23 of bracket 22 is secured to an arm 24 which is extendeddownwardly and secured to one of the members of the main frame. Theseparts may be of any suitable or usual construction, the disk and scraperserving as means for cutting, lifting and turning the furrow-slice.

A guide 30 comprises a wall 31 disposed to overlie the furrow-slice asit is projected outwardly and forwardly or rearwardly by the cutting andturning means to confine the slice against excessive upward travel.Guide or shield 30 comprises a downwardly extending wall 32 on its outerside which limits the outward movement of the furrowslice projected fromthe cutting and turning means. The walls 31 and 32 of the guide areadapted to receive furrow-slices proje-cted from the disk and scraper inall conditions of soils and confine one side of the slice in a definitepath to positively control its delivery to the ground. At the lowerportion of the side-wall 32 of: the shield is formed a stop-ledge 38extending throughout the length of the shield and into position toprovide a positive step or guide on which the outer edge-portion of theinverted upper face of the slice will ride and whereby the slide will bepositively limited against excessive turning movement. This stop andguide 33 extends inwardly at sufficient angle to the sidewall 32 to beengaged by the slice and so that the slice will be arrested by the stop.

Different slices or the same slice in different conditions, are,generally speaking, differently projected by the cutting andlifting-means. These different conditions make it necessary at times toadjust the moldboard scraper to different points on the disk, resultingin the projection of the furrow-slice in a different path. So also,irregularities in the soil must be provided for in thecontrolling-means. The shield is of sufficient length to receive andguide the slices as they may be differently projected under diflerentconditions and whether the slice is projected forwardly, laterally orrearwardly with respect to the axis of the disk. In order that theshield may be properly disposed to receive and guide a thin furrowsliceso that it will also be properly disposed to receive and guide a thickerfurrow-slice, the shield is mounted so its position may be varied by thethicker furrowslice, being secured to a flexible supportingbar 34: so itis free to yield vertically to any undue pressure of the furro.wsliceagainst the top of the shield, thus preventing clogging and makingprovision for the passage of irregular or different sized furrow-slicesso substantially all will be guided by the shield and ride on stop-ledge33 without excessive disintegration of the slice. Flexiblesupporting-bar 3i is secured at its front end to a bar which in turn isbolted to the main-frame of the plow. Resultantly, of this construction,furrow-slices differently projected by the disk or slices of differentsizes, or more or less irregular in shape, will all be received by theshield and restrained against excessive turning movement by stop 33 andbe guided thereby to the ground. Stop-ledge 33 extends rearwardly anddownwardly to sustain and guide the outer portion of the furrow-slice asit passes under or along the side-wall of the shield and until it is inclose proximity to the ground, and is effective in limiting the sliceagainst excessive turning, whether such re sult from the differentconditions of the soil or the diiferent operation of the cutting andlifting-means. Furthermore, the same relation of the stop-ledge andshield is always maintained, despite any variation of the relation ofthe guide to the cutting and turning-means.

A bar l0 beneath guide 30 extends rearwardly and downwardly and isdisposed a short distance below and inwardly of stopledge 33 so that ifthe furrow-slice should be too small to be caught and guided bystop-ledge 33, bar 4.0 will arrest the slice and guide it rearwardly tothe ground. Thus any tendency of a small slice to turn over on its edgeor excessive twisting thereof is effectively overcome by the bar 40.Adjacent the rear portion of guide 30 said bar is bent inwardly to forman arm 4:1 to catch and sustain the inner edge-portion of the invertedfurrow-slice as the slice is being delivered to the ground and toexercise a restraining influence on the inner edge of the slice. Thisbar may be formed of an extension of the bar 35 to which the shieldsupporting-bar 34 is secured, and is slightly yielding so that the rearworking end may yield slightly when unduly strained by the furrow-slice.If the slice is not turned sufficiently in transit to the ground thenarm 41 guides or restrains the inner edge of the slice to deliver theslice in correct position face downward on the ground.

When the plow is in operation, the furrow-slice cut and lifted by theconcavo-convex disk will be turned upwardly and outwardly and eitherforwardly or rearwardly, depending upon the form and relative positionof the disk and mold-board scraper. The mold-board scraper and disk willproject the disk upwardly and outwardly and the acquired impetus willcause it to coninue its turning movement. In transit from the turningand lifting-means the furrow-slice will be guided by the shield 30 y andthe outer edge portion of the slice will be arrested by the stop-ledge33 to positively limit the furrow slice from excessive turning-movementand guide 30 will prevent excessive outward or upward movement thereof.By reason of the construction set forth, either an irregular furrowsliceor furrow-slices of different sizes or slices differently pitched by theplow, will all be guided and controlled so that each will be deliveredonto the ground in truly inverted position and without undesireddisintegration. lVhile the furrow-slice is passing under and within theshield walls, the outer or front edge of the slice will ride alongstop-ledge 33, or if an unusually small slice is cut and is notsufficiently projected outwardly, it may ride on bar 40; The slice is,in nearly all instances, guided onto the stop-ledge 33 by guide 30, anda better result is obtained'when the ledge is mounted in fixed relationto said guide. As the furrow-slice reaches the rear portion of theshield, the rear curved end of bar 40 serves to sustain and guide therear or inner edgeportion of the inverted slice and furthermore, if theslice has not been sufficiently turned before passing over said bar suchportion will be restrained and guided by said bar so the slice will besufliciently turned to prevent the slice from being laid on one of itssides. Resultantly, the structure aforesaid serves to efiectively guideand control furrow-slices resulting from different conditions of thesoil or operation or construction of the turning and liftingmeans, sothat all will be correctly delivered onto the ground and inverted.

The invention is not to be understood as restricted to the preciseconstruction illustrated and described but may be modifieu within thescope of the appended claims without departing from the spirit and scopeof the invention.
